Origin of net-veined and mixed-magma ring intrusions
… of highly evolved tholeiitic magmas ranging from ferrobasalt through basaltic-andesite and andesite, to rhyodacite and rhyolite. The magmas represent both fractionates of basaltic magma and hybrids of silicic, intermediate and mafic magmas. Strontium isotope data also indicate that most of the …

Microstructural evolution of silicate immiscible liquids in solidifying ferrobasalts
Evidence of silicate liquid immiscibility in ferrobasalts is provided by co-existing Fe- and Si-rich melt inclusions and Fe-rich droplets dispersed in the Si-rich glassy mesostasis of rapidly cooled rocks. Crucially, the different physical properties of these unmixed liquids mean that they may …
